Welcome to mybulova! Your watch looks to be a His Excellency, like this one. The date code on the movement is a triangle (1945), which indicates the movement was replaced at some point. It's not that uncommon, like a much loved car having the motor replaced with another used one.
1950 His Excellency "SS", noting replaced movement.
Thanks for sharing it!

Welcome to MyBulova. 1950 His Excellency with a replaced movement is a good match. I guess you could call it a new OLD motor since the movement is an earlier model than the watch. I think by 1950 the movement would have been a 7AP. It is also interesting in that the movement has both a triangle and a circle date code. Every so often we see a movement with two date codes.
